Lowest cost for point production

I am looking to buy some new hardware. Watching my AX2 fold is painful. I'll have a case, psu, hdd, and if it uses DDR2, memory. What mobo/PCU combo will give me the highest points with the lowest capitol costs?
Is it worth going quad? or will cheap dual core work better?
Give your thoughts, but you have better also have numbers to back them up.

1. Q6600 at default clock (2.4GHz) - 3100-3800 PPD
2. Q6600 at 3.5GHz: 3500-4500 (yes, WUs vary that much)
Q6600 with two clients running will outproduce a similarly clocked Core 2 Duo by 50% or better.
Ad an Nvidia 8800GT/S/X video card using the GPU2 client, and you can reach up to 6000PPD on a single machine - 1XWinSMP + 1XGPU2. Look carefully, and you can find 8800GT cards on the used market for less than $125. (I just made a deal on a new GT/512MB/600MHz, new, for $105 shipped.) You can find new 8800GTS cards, after rebate, for less than $135. Look for 500MHz core clock minimum. Onboard RAM quantity and speed doesn't seem to matter much for Folding.
I do not have figures for running GPU2 alone. I have just purchased an 8800GT on a trading post and will soon be experimenting with that.
If you are willing to purchase on the pre-owned market, you can easily find a good Socket 775 overclocking board and a Q6600 G0 for $300 or less. Shop carefully and you can find retail, new for around $300.
For maximum points with Quad, you will need a good PSU and a good CPU heatsink. Q6600s are rather easy to overclock given good cooling and solid vCore supply.
There are a boatload of G31/G33 mobos that run DDR2. What gets me is that they run from $40 to $240. The features are all over the place.
Any tips on a reliable one. I do want on-board graphics to minimize power use and cost.
If you are going to go DDR3, then go X38/48.
The Gigabyte GA-G33M series are great. They use high quality components that also consums less energy. I have two of them (GA-G33M-S2) folding 24/7 for 8 months now and with no problems at all. Or else Asus G33 alternative are also very good.
And if you decide later that you do want to run a very moderate overclock on a Q6600, you can pretty much get away with just setting the fsb speed to 333 and have an instant 3 GHz processor. Most all of the G0 Q6600 procs can run 3 GHz without messing with vcore too.
I have become a firm believer in GPU folding. The 8800GT is producing more than an overclocked Q6600 running two WinSMP clients simultaneously. Lowest cost point production? If your computer has a PCI-e 16 slot and a competent power supply, GPU Folding@Home is the way to go.
The good news is that Nvidia 8800 cards are becoming inexpensive. I picked up my XFX 8800GT on a forums trading post, new, still sealed for $105 shipped. (Mudd, the seller was g0dm@n.) 4500PPD - just from the video card.
Icrontic's GPU2 Folding thread.
XFX 8800GT 256MB (Alpha Dog Edition) - 4700PPD rough average
MSI 8800GT 512MB (NX8800GT 512M OC) - 5400+PPD
The most I paid for either of those was $125 shipped and it was used. That is better bang for buck than any CPU at any real world clock rate.
